FIELD OF THE INVENTION

The present invention relates generally to a fan, and more particularlyto a new circumferential air conditioning fan that can fan in multipledirections at the same time.

BACKGROUND OF THE INVENTION

Fans save more electricity than air conditioning; therefore, many usersare still using fans for indoor or outdoor air conditioning systems. Thestructure of the conventional fan is familiar to users, and it mostlyhas a fan blade placed in a certain style of housing or cover. The fanblade is driven by a motor to form the air stream by circulating the airby fan blade; however, the conventional fan has the following problems.

1. When using the conventional fan, because its fan blade faces peopledirectly, the air formed often is too forceful, and would causediscomfort after a long period of time.

2. Another problem is that the conventional fan is designed with for asingle direction. Though some have functions of auto turn, it is stillcirculating air in one direction, and unable to achieve the effect ofmulti-directional circulation at the same time.

Thus, to overcome the aforementioned problems of the prior art, it wouldbe an advancement in the art to provide an improved structure that cansignificantly improve the efficacy.

To this end, the inventor has provided the present invention ofpracticability after deliberate design and evaluation based on years ofexperience in the production, development and design of relatedproducts.

BRIEF SUMMARY OF THE INVENTION

1. The circumferential air conditioning fan provided in the presentinvention mainly focuses on the new design of the centrifugal fan 20 ofthe air inlet 12 of the rotary diversion component 22 that is placed inthe containing space 1 1 of the housing. The fan guides the airflow ofthe air inlet 12 and turns it into circumferential airflow, so that theair from the circumferential air conditioning fan is gentler than theconventional fan, and it can increase the degree of comfort using thefan.

2. When the fan is operating, it can provide circumferential airflow in360° at the same time, and let the people within all directions of thefan receive constant air. Under the same circumstances, the number ofthe fans of the present invention needed is much less than theconventional fan. It provides gentler air quality; therefore, it isapplicable for home and business office use.

3. By adding a mist sprinkler 50 on the circumferential air outlet 13 ofthe housing 10, it causes the air from the circumferential airconditioning fan to be spread further, and adds moisture in the air,which gives people an after rain freshness.

4. By the structural design, the expanded rim 14 at the air inlet 12 ofthe housing 10 to has a certain degree of stopping effect for the mistthat comes out of the mist sprinkler 50 to reduce the amount sucked inthrough the air inlet 12 and to avoid excessive humidity of thecontaining space 11 of the housing 10, which may affect the life of thedrive motor 30 and its circuits.

5. The design of the casing 70 placed on the end of the air inlet 12 ofthe housing 10, when the air inlet 12 is facing upward, can createraining stopping and decorative effects.

Although the invention has been explained in relation to its preferredembodiment, it is to be understood that many other possiblemodifications and variations can be made without departing from thespirit and scope of the invention as hereinafter claimed.

DETAILED DESCRIPTION OF THE INVENTION

The features and the advantages of the present invention will be morereadily understood upon a thoughtful deliberation of the followingdetailed description of a preferred embodiment of the present inventionwith reference to the accompanying drawings.

As shown in FIGS. 1-3, there is a preferred embodiment of thecircumferential air conditioning fan.

A housing 10 is round, and a containing space 11 is placed internally.One of the containing spaces has at least one air inlet 12, and the sideof the containing space 11 has a circumferential air outlet 13.

A centrifugal fan 20 is placed in the containing space 11 of the housing10 that is close to the circumferential air outlet 13, and thecentrifugal fan 20 includes several centrifugal blades 21 that arespaced in a circle and rotary diversion component 22. The first end ofthe rotary diversion component 22 is placed correspondingly to the airinlet 12 of the main housing, and the second end is placedcorrespondingly to the air outlet 13. The rotary diversion component 22of the present invention includes a first arc rim 221 that is on the airinlet 12 of the centrifugal blade 21, and a second arc rim 222 that ison the end of the circumferential air outlet 13. It blows air by theturning of the centrifugal fan 21 from the air inlet 12 on top of themain housing to the directions of the circumferential air outlet 13.

A drive motor 30 is placed in the containing space 11 of the mainhousing 10, and the output axle 31 of the drive motor 30 can beconnected with the axle holes in the center of the centrifugal fan 20 tomake the centrifugal fan 20 turning.

A stationary stand 40 includes a first assembly component 41 and asecond assembly component 42, and the combination of the first assemblycomponent 41 is connected with the main housing, and the second assemblycomponent 42 may be placed or assembled on the designated environment orfoundation.

The stationary stand 40 of the present invention is a floor structure.It has a first assembly component 41 on the top that has through hole43, and by screwing the screw hole 14 designated on one end (the bottomend) of the air inlet 12 of the main housing to achieve the positioning.

Through the above structure and design, the operation of the revolvingengine disclosed by the present is explained as follows:

As shown in FIG. 3, when the centrifugal fan 20 is turning, it may usethe design of its rotary diversion component 22 and generate thevertical airflow A1 through the air inlet on top of the housing 10, andguide it and turn it into horizontal airflow in 360° and generatecircumferential airflow A2.

Among them, the circumferential air outlet 13 of the main housing 10 canhave a mist sprinkler 50 added, and the mist sprinkler can be made ofconduit 51 and nozzle 52. The spray of the mist can be controlled by thepressure driven device from the far end. The nozzle 52 can be spaced ina circle on the external part of air outlet 13 of the main housing 10,so that the mist spray when the air is blown can be spread further(please see FIG. 3), and by adding the mist primarily is to increase thehumidity in the air and give people a refreshing feeling.

Among them, the air inlet 12 of the main housing 10 can have an expandedrim 15. The placement of this expanded rim 15 is related to the mistsprinkler 50 mentioned above, and the expanded rim 15 can form a stopperon the edge of the air inlet 12 of the housing 10 to create certainstopping effect for the mist from the mist sprinkler 50, and to reducethe amount the mist is being absorbed by the air inlet 12, and to avoidthe heavy humidity inside the containing space 11 of the housing 10 toaffect the life of the drive motor 30 and its circuits.

Among them, as shown in FIG. 4, the stationary stand 40B mentioned abovemay also be a stand with suspension on one end of air inlet 12 in thehousing. The air inlet 12 of the housing is a net support 61 of theplace in the center, so that the first assembly component 41 of thestationary stand 40B can be placed on the plate 60. The second assemblycomponent 42 of the stationary stand 40B may be placed on the ceiling,so that the housing 10 may be suspended on the ceiling, and by so doingto make the suspension of the circumferential air conditioning fan.

Among them, as shown in FIG. 5, the stationary stand 40B can also be awall-mounted stand. The difference between this style and the abovementioned embodiment is that the stand of the stationary stand 40B isassembled horizontally, so that the second assembly component 42 of thestationary stand 40B can be placed on the wall. The air inlet 12 of thehousing 10 can suck air horizontally facing the wall, and thecircumferential air outlet 13 can circulate the air vertically.

Among them, as shown in FIG. 6, the air inlet 12 of the housing 10mentioned above has a casing 70 where it is spaced, and the casing canbe locked in by the holder 71 on the central plate 60 of the net support61 of the air inlet 12. The design of the casing 70 is when the airinlet 12 is assembled facing upward, it can create the effect of rainingstopping. When the circumferential air conditioning face is placedoutdoors (as shown in FIG. 7), it can prevent the rain from falling intothe housing 10 through air inlet 12 and affect the life of the drivemotor 30 and its circuit. Of course, the casing 70 on the other hand canbe decorative.
